摘要: 以计算机联锁系统(Computer Based Interlocking,CI)为研究对象,分析了CI系统的通信板、控显及维护机存在的信息安全问题。研究结果表明CI系统存在漏洞被利用的风险,也为基于通信的列车控制系统(Communications Based Train Control,CBTC)信号系统信息安全防护提供了思路。

关键词: 分析, CI系统, 信息安全, CBTC信号系统

Abstract: This paper mainly focuses on CI system and analyzes the information security problems existing in the communication board, MMI and maintenance machine of CI system. The research results show that CI system has the risk of vulnerability being exploited, which also provides ideas for information security protection of CBTC signal system.

Key words: analysis, CI system, information security, CBTC signal system
